Solar wind parameters, as measured by the ACE spacecraft, reflected
waning CH HSS effects. Solar wind speeds exhibited a slow, but steady
decrease from just over 700 km/s near the beginning of the period, to
near 540 km/s by the end of the period. Total magnetic field began at 9
nT, but gradually decreased to 5 nT by the end of the period. The Bz
component varied between 8 nT and -5 nT. The phi angle began the period
oscillating between positive and negative sectors before becoming mostly
positive (away) after 04/1400 UTC.

About

Aurora Service was set up by me (Tony) in my spare time. I am a computer programmer and aurora watcher, so I combined both experiences to create this site to help aid my aurora viewing. It has kept growing since.

We now have 3 Aurora Service websites providing aurora information in 3 continents.
